STUDY OBJECTIVES: The use of positive airway pressure (PAP) in children is a complex process determined by multiple factors. There are limited data on the response of the pediatric population to PAP therapy at home. The goal of the study was to examine real-world responses using PAP home monitoring in children with obstructive sleep apnea (OSA). METHODS: The study included PAP therapy data for 195 children aged between 1 month and 18 years, with OSA and PSG baseline study. We collected demographics, clinical variables, and PSG parameters in all study subjects. The individual response to PAP therapy was calculated comparing the AHI in the initial PSG with the mean AHI provided by the download of PAP devices. Multivariate models (logistic regression) were used to examine the predictors of positive PAP response defined as a reduction in AHI ≥75%. RESULTS: We found excellent responses to PAP therapy in children (median 85% AHI reduction). However, there was substantial heterogeneity in AHI reductions while on PAP therapy. Best PAP responses were linked to more severe OSA and higher PAP levels. We also identified that the response to PAP was higher in obese children, and lower in males. The best predictive model for individual PAP response was biological sex, obesity, and OAHI >=20/hr (area under ROC of 0.791). CONCLUSIONS: Real-world data shows that PAP is overall an effective therapy in children, but the response is heterogeneous. OSA parameters and individual factors can be used to predict individual AHI reductions while on PAP and optimize PAP responses at home.
